OP, you might not have to dig the sample out again. Just saw the post re:fits in a baseball and the anon who posted crinoid is not far off the mark.

Assuming the sample is Ordovician, I reckon the fossil is of a rugose coral. They are usually single corals and don't form colonies, but looks like several single rugosa have stacked themselves on each other like a colony. However, not a paleobiologist so this could still be a single rugose coral and that's just how it grows.

Ohhhh, that there? THAT is an ancient rugose coral (a.k.a. horn coral) only distantly related to today's corals. (Rugose and Tabulate corals are long extinct; all corals present today are Scleractinian corals.)

Pic related, it's a solitary rugose coral like the one you've got in that rock..
